Wangda Tan commented on YARN-796:
---------------------------------

[~vmhp], Really appreciate sharing node label use cases in HP.

it's great to hear HP uses node label quite well. Very helpful to people who want to try node
label.

> It will be useful for admins to specify labels for nodes. Examples of labels are OS,
processor architecture etc.
> We should expose these labels and allow applications to specify labels on resource-requests.
> Obviously we need to support admin operations on adding/removing node labels.
